Use of the current
|Tower power station
Many heliostates (mobile, computer-controlled mirrors) surround a tower. The
mirrors are aligned sequentially to the sun and reflect the sunlight on the absorber.
Inside this device a heat liquid (usually water) is heated up, brought partially to
1000°C, and to evaporation. This steam propels the turbines which are situated
in the tower and produce current.
|Farm power stations
These power stations carry the names as they are used actually only on American farm areas.
Special solar collectors focus the sunlight in round mirrors, where the transfer fluid (in these power stations it is oil) is heated up. The heated oil lets water evaporate, which propels again steam
